Subject [jira] [Commented] (HBASE-4269) Add tests and restore semantics to TableInputFormat/TableRecordReader
Date Fri, 16 Mar 2012 16:39:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4269?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13231356#comment-13231356

Jonathan Hsieh commented on HBASE-4269:
---------------------------------------

Jan, 

When I did this patch, the two versions had different error recovery path and I made them
similar.  UnknownScannerException is a subclass DoNotRetryIOException so I chose that instead.
 

I'm assuming this is causing some pain now -- how is this affecting the job you are running?
(is it catching and rethrowing other exceptions as well?) 

If there is something we need to change I'm fine with that.  Let's file a new issue -- this
patch has been in included in a few releases now.

> HBASE-4196 Modified the semantics of failures in TableImportFormat/TableRecordReader,
and had no tests cases.  This patch restores semantics to rethrow when a DoNotRetryIOException
is triggered and adds test cases.
